Frog Bikes, a UK-based manufacturer of premium children’s bicycles, has unveiled an innovative partnership with Norwegian tyre company reTyre. This pioneering collaboration will see Frog Bikes equipping its bikes with sustainable tyres from 2025, marking a significant step in the cycling industry's journey towards sustainability.

Jerry Lawson, Co-founder of Frog Bikes, expressed his enthusiasm about the partnership, “We are thrilled to collaborate with reTyre, a brand that shares our passion for innovation and sustainability. This partnership allows us to further our commitment to the environment while providing our young riders with the best possible cycling experience.”

The collaboration is a testament to Frog Bikes' unwavering commitment to sustainability. It focuses on transitioning Frog Bikes’ entire range to reTyre’s fully recyclable, bio-based pneumatic tyres, ensuring a greener future for the cycling industry.

reTyre, known for its groundbreaking approach to sustainable tyre production, utilizes recyclable bio-based materials and innovative manufacturing methods to achieve lower emissions. The company claims its tyres deliver exceptional performance while minimizing environmental impact.

Frog Bikes aims to complete the full transition to reTyre tyres across its entire product line by the end of 2025. This move aligns with growing consumer demand for eco-friendly products, particularly within the children’s goods market.

“Our tyres are made with renewable and bio-based materials that do not need to be vulcanized, meaning that we can easily reuse the material at end-of-life. Our verified Life Cycle Assessments show that we are then able to reduce emissions by 68-82 percent compared to conventional tyres”, says Ben Evans, Commercial Officer at reTyre. “It’s great to work with a brand like Frog Bikes, who embraces changes for the planet’s benefit.”

 Towards Net Zero Since embarking on their sustainability journey in 2019, Frog Bikes has cut emissions per bike by 25 percent. “We’ve achieved this by transitioning to renewable energy, redesigning our bikes to use less material, virtually eliminating plastic packaging, and moving away from air freight”, explains Anna Drew, Head of Sustainability at Frog Bikes.

 “Exploring sustainable materials, like post-consumer recycled aluminium for our frames and partnering with reTyre for lower-emitting tyres, are crucial to our commitment to halve emissions by 2030 and achieving Net Zero by 2050.” “We are excited to present the Frog bike equipped with sustainable tyres alongside our full range of sustainable tyre products at this year’s event,” Evans concludes.

Pirelli has introduced two new versions of its P Zero tyre for the latest Porsche 911 GT3, extending its supply across the entire 911 range. The P Zero R and the P Zero Trofeo RS have been developed to meet specific performance needs, using experience gained from tyres created for the Porsche 911 GT3 RS.

The P Zero R is designed for daily use on high-performance cars. Its compound, developed for the new GT3, is intended to deliver strong grip on varied surfaces, including in wet conditions. Pirelli says the tyre operates across a wide temperature range and maintains performance even in less favourable situations. The structure differs between the front and rear tyres to balance steering precision, sensitivity and control, especially under high loads.

The P Zero Trofeo RS sits at the top of the P Zero range and targets track driving. The tyre is designed to sustain grip and precision over long sessions, even under demanding conditions. Pirelli reports that expertise from its work on the Trofeo RS for the 911 GT3 RS has been applied to the version now created for the latest 911 GT3.

Tailor-made versions of the Trofeo RS have also been produced for other models, including the Porsche Taycan Turbo GT. Both new tyres for the GT3 feature Pirelli’s Perfect Fit strategy, which focuses on bespoke development for each vehicle model. Each tyre carries an “N” marking on the sidewall to reflect its dedicated development for the 911 GT3.

Development took place using virtual techniques at Pirelli’s research centres in Milan and Breuberg, reducing both development time and the number of physical prototypes by 30 per cent.

The new Renault Clio will feature Continental's EcoContact 7 tyre as original equipment for its global launch. Approved in numerous countries, the compact car will be fitted with this model in two specific sizes: 195/60 R16 and 205/45 R18. Both variants have earned the highest possible ratings on the EU tyre label for fuel efficiency and low rolling noise, underscoring their performance credentials.

This high performance stems from several integrated technological advancements. A newly formulated rubber compound works in concert with Continental’s Smart Energy Casing, which employs innovative materials in the tyre’s internal structure to minimise friction and rolling resistance. Further efficiency gains are achieved through an aerodynamically refined sidewall. This design incorporates a dimpled texture, inspired by the surface of a golf ball, to smooth airflow and reduce the energy required to keep the tyre in motion.

Alongside its energy-saving properties, the tyre is engineered for refined acoustics. A specifically designed Silent Pattern tread layout alters the arrangement and angles of the tread blocks to target and dampen the frequency of noise typically produced during low-speed urban driving. This focus results in a reduction of rolling noise, enhancing comfort for those inside the vehicle and contributing to a quieter environment for pedestrians and city residents alike.

Giti Tire has expanded its AdvanZtech EV Ready line with the launch of the GitiWinterW2, its first winter tyre designed for electric, hybrid and conventional vehicles. The company said the new model is now available for ordering for the 2025/26 winter season.

The GitiWinterW2 will be offered in 17 sizes ranging from 15- to 20-inch rims. All products carry the AdvanZtech EV Ready sidewall mark, indicating suitability for internal combustion vehicles as well as mild hybrid, plug-in hybrid and battery-electric models.

The range is intended to cover a wide span of the European car parc, from small cars such as the Fiat 500e to larger vehicles including the Tesla Model 3, Volkswagen Tiguan and Volvo XC60 PHEV. Giti said each tyre has been tuned for EV-specific demands such as torque management, while maintaining low rolling resistance and strong performance on snow and wet roads.

The manufacturer highlighted three core attributes for the GitiWinterW2: a quiet and comfortable ride, strong safety characteristics and precise control in winter conditions.

The winter tyre joins the GitiSportS2 and GitiSynergyH2 summer patterns in the EV Ready strategy first announced in August 2024. All three products were developed using Giti’s AdvanZtech R&D framework at its European Research & Development Centre in Hannover, Germany.

Fabio Pecci-Boriani, Deputy General Manager for Product Planning PCR and LTR at Giti Tire’s European R&D Centre, said the company aimed to give both drivers and dealers greater clarity as electrification reshapes the market. “The Giti brand was among the first in the mid-market to introduce an EV ready concept, ensuring maximum flexibility and product clarity for dealers and peace of mind for drivers.”

He added that winter conditions pose specific challenges for electrified cars. “As is proven winter can have an impact on the performance of part-electric and electric vehicles with lower temperatures reducing battery range and immediate torque levels being tricky on slippery roads, the Giti AdvanZtech EV ready GitiWinterW2 goes a long way to addressing these issues.”

Giti said its EV Ready strategy remains a central pillar of its European product plans as the shift towards hybrid and battery-electric vehicles accelerates.
